Serial Port Communications and Commands
Command Explanations
The following example shows the steps necessary to pulse Remote Bit 5
(RB5):
=>>CON 5 <Enter>
CONTROL RB5: PRB 5 <Enter>
=>>
You must enter the same remote bit number in both steps in the command. If
the bit numbers do not match, the relay responds
Invalid Command.
See Remote Control Switches on page 7.9 for more information.
COP m n Command (Copy Setting Group)
Copy relay and SELOGIC control equation settings from setting Group m to
setting Group n with the COP m n command. Setting group numbers range
from 1 to 6. After entering settings into one setting group with the SET and
SET L commands, copy them to the other groups with the COP command.
Use the SET and SET L commands to modify the copied settings. The relay
disables for a few seconds and the ALARM output pulses if you copy settings
into the active group. This is similar to a Group Change (see Section 7: Inputs,
Outputs, Timers, and Other Control Logic).
For example, to copy settings from Group 1 to Group 3 issue the following
command:
=>>COP 1 3 <Enter>
Copy 1 to 3
Are you sure (Y/N) ? Y <Enter>
Please wait...
Settings copied

PAS Command (Change Passwords)
The relay is shipped with factory default passwords for Access Levels 1, B,
and 2 as listed below:
The PAS command allows you to change existing passwords at Access
Level 2. To change passwords, enter PAS x, where x is the access level whose
password is being changed. The relay will prompt for the old password, new
password, and a confirmation of the new password.
